High-Efficiency Urinal (HEUs) Testing

High-Efficiency Urinals (HEUs) use approximately 0.5 gallons per flush (gpf) or less - at least one half of the amount of water used to flush the average urinal. One HEU can save 20,000 gallons of water per year with an estimated 20-year life. High-Efficiency Urinals contribute to long-term decreases in water usage and water bills, as well as promoting the sustainability of our environment.
 
The Zurn EcoVantage® Ultra Water Saving Urinal System reduces water consumption by 85% compared to a typical one gallon urinal. It conserves more than 30,000 gallons per year. The low consumption Zurn EcoVantage Pint Urinal uses just one pint (16 ounces or 0.5 liters) per flush. It promotes water conservation while providing the sanitary flushing action of a standard urinal. It is an environmental alternative to controversial waterless urinals that rely on unwanted, unsanitary plastic oil disks that must be changed on a regular basis. The plastic oil disks are not biodegradable and eventually end up in a landfill.
 
The WaterSense label is used on HEUs that are certified by independent laboratory testing to meet rigorous criteria for both performance and efficiency. Only HEUs that complete the third-party certification process can earn the WaterSense label.

Ensuring HEU performance requires a paired performance system approach that will operate over the entire pressure range spectrum. For a manufacturer like Zurn Industries, performance testing is imperative to bringing high quality and superior performing fixtures to the market. 

Two of the recognized criteria for performance testing within the U.S. are ANSI/ASME A112.19.9 Hydraulic Performance Requirements for Water Closets and Maximum Performance Testing (MaP Testing). These tests were developed to allow fixture designers and others (cities and municipalities) a way to standardize and benchmark performance. All fixtures must pass these test criteria. Constant and vigilant testing is critical to the HET/HEU success and market acceptance. ANSI performance tests include:
 
1.  Water Consumption: The amount of water consumed per flush.
2.  Ink-Line: Test is designed to ensure proper bowl rinse.
3.  Dye Test: Test is designed to evaluate bowl water exchange.
4.  Trap Seal: Test to ensure the fixture fills and has proper seal.
5.  Ball Removal: Tests evacuation.
6.  Granule Removal: Tests evacuation.
7.  Line Carry: Test determines how well solids are carried through the drain line.
8.  Splash Test: Test ensures that excess splash does not occur during flush cycle.
